A traveled to the top of a Volcano in Hawaii to capture this: Saturn briefly covered by the moon. One of the most difficult shots I’ve captured and a bucket list moment, this event gave me a new perspective on the solar system.

I’ll have it available in print for a short time.

@johanjanssen42 @AlmanacHotels Doesn't sound like a 4 star hotel experience to me ;-)

A delivery startup that “won” home delivery in the Netherlands is called Picnic.

They deliver within a half-hour slot. Need to order days ahead. You need to apply on a waitlist & wait until spots free up.

It is the most reliable option. Their trucks: https://t.co/rniRIAQcP3

@eliasnogueira Thanks for joining!

So I guess my choice [editor's note: admit, it's just laziness] to not upgrade to macOS 14 yet comes with some advantages... Be advised that macOS 14.4 on Apple silicon may lead to crashes in your Java applications!

[Java @java]

Java users on macOS 14 running on Apple silicon systems should consider delaying the update to macOS 14.4. For further information: https://t.co/NnrPpFwRDh

Come and learn how Picnic evolves its warehouse systems architecture to keep up with our growth and increasing degree of robotization!

[Bert Jan Schrijver @bjschrijver]
